It's important to note that while "goy" is the literal translation, it can sometimes carry negative connotations in Yiddish, particularly in older usage. This is due to historical and cultural context, where it was often used to refer to non-Jewish people in a discriminatory manner.
In modern usage, it can be used in a neutral way, simply to refer to someone who is not Jewish. However, it's always best to be mindful of the potential for misunderstanding and use alternative phrases if possible, like "a non-Jewish person" or "someone who is not Jewish."
